fastboot reason: flash failure?

[r3m1x]

so i recently updated to the latest update for my razr maxx hd. i tried going back to the previous version because i noticed that my rootkeeper didn't root my phone and i think in doing so, might of damaged the boot process and now i keep getting the AP Fastboot flash mode screen every single time i reboot my phone. i have to press power, up and down volume to select "normal startup". is there anyway i can fix this little problem? or maybe i'm just doing something wrong. can anyone please help me out? i also found out that it's not possible to downgrade and so i'm forced to wait for a new way of rooting my phone. =/ can somebody help me out please? thank you so much!

btw, i used Droid Razr Utility 1.82 (option 1) to try and downgrade and after this, the problem started.

is it possible to use RSD and restore the original flashboot files?

I have a question and i hope someone see's this in the near future. I recently rooted my razr maxx hd and also unlocked my bootloader. now having said that, i downloaded the razr toolbox from play store and was looking through the tabs that are available. after clicking on the meters tab, my phone showed a darkened "working" box and then my phone shut off. it then rebooted and when i went to unlock my phone, i had a prompt that read--"unfortunately, system ui has stopped working." Now i have no onscreen soft keys. (ie Back, Home, Search.) Looking to figure out what i need to do to restore these things so i can use my phone again.

Also i know i am probably not in the right thread, but i am in a bit of a hurry to try and get this resolved, so if someone see's this and knows anything about it and can repost, that would be great.

thanks for any help.
